EXHAUST HIGH TEMP FAULT (D19)
An exhaust high temperature fault occurs when the exhaust probe is detecting a tumbler temperature that is 20° F
above the maximum dryer temperature set point for more than 10-seconds.
BLOCKED COIN DROP (D5) (Coin Models Only)
This fault occurs if the control senses a blockage in the coin input. If the coin input is blocked for more than
8-seconds the control will go to out of order and will not allow the control to start a cycle. This fault has both automatic
and manual fault clearing. If the condition is corrected the control will recover from out of order immediately after the
blockage is no longer seen.

EVENTS

A radiant sensor fault count will occur when a gas model dryer attempts to turn on the burner system and never
receives a 120V return signal within a predefined time.
BURNER IGNITER FAULT COUNT (E2)
A burner ignition fault count will occur when a gas model dryer attempts to turn on the burner system and receives a
120V on the burner return signal but it does not transition to a 0V return signal within a predefined time.
EXHAUST HIGH LIMIT (E3)
This location is a count of the times that the exhaust high limit has been sensed in the open position.
BAD COIN COUNT (E7)
This location is a count of all the bad coin occurrences that were detected from the coin input.
REVERSE ROTATION SENSOR FAULT
REVERSE ROTATION SENSOR FAULT is identical to FORWARD ROTATION FAULT, however it pertains to the
reversing drive output instead of the forward drive output.
S.A.F.E. DISABLED – WATER NOT CONNECTED
This event pertains only to machines with a fire detection system. If the control senses a lack of water pressure, this
event will appear.
